This week marks the last full week of operations for watercraft inspection stations as we transition into Fall. As of Oct. 1, watercraft inspection operations will move from roadside inspection stations and occur at Cave Rock and Lake Forest launch ramps for the winter season.
This season marks 11 years of Lake Tahoe’s Watercraft Inspection Program. Under the program, every motorized watercraft is inspected to ensure it is Clean, Drained, and Dry and not carrying aquatic invasive species (AIS) before launching at Tahoe. Thanks to the diligence of boaters and inspectors, no new aquatic invasive species have been detected in Lake Tahoe since the program launched in 2008.
Inspectors examined nearly 8,000 watercraft this season, 50% of them arrived Clean, Drained, and Dry. This is evidence that boaters continue to come to watercraft inspection stations prepared. Eleven watercraft were found carrying invasive mussels and 29 were harboring other species. Vigilance is required to protect Lake Tahoe’s waters from new exposures to invasive species.
Each vessel found harboring invasive species was decontaminated before being allowed to launch in Lake Tahoe. The largest number of decontaminations occur on vessels containing standing water, which
may harbor aquatic invasive species. Boaters are encouraged to continue to be a part of the solution by cleaning, draining, and drying their vessel before launching in any waterbody. This includes both motorized and nonmotorized watercraft.
During winter season operations, Tahoe Resource Conservation District inspectors will conduct aquatic invasive species inspections and decontaminations from 6 a.m. to 4 p.m. seven days a week, weather
permitting at Cave Rock and Lake Forest launch ramps. All motorized watercraft without intact Tahoe Inspection seals will be required to get an inspection during daylight hours.

What was once a dull gray shipping container has been transformed into a work of art at the watercraft inspection station in Meyers, California. The container houses equipment used to decontaminate boats arriving at the station that might harbor aquatic invasive species.
Now greeting boaters will be a colorful and creative mural painted by local artists and students. At the same time the mural puts the Clean, Drain, and Dry message front and center.
Shipping containers are the utilitarian cargo-carrying crates of the open ocean, hulking large metal boxes that began life transporting goods piggybacked on top of one another, bound for destinations around
The Tahoe Regional Planning Agency and the Tahoe Resource Conservation District use a number of these shipping containers at various watercraft inspection stations around Lake Tahoe.
This summer TRPA commissioned South Tahoe High School teacher and artist Matt Kauffmann to transform one of the big gray boxes into a work of art. Kauffman and several of his current and former students spent many hours over the span of four nights to complete the mural project.
“Nobody said fighting aquatic invasive species couldn’t also be beautiful at the same time,” said Dennis Zabaglo, manager of TRPA’s Aquatic Invasive Species Program. “This mural emphasizes our Clean, Drain,
and Dry message, in a colorful way that grabs boaters attention.
Would you like to see this work of art for yourself? It’s located at our boat inspection station in Meyers, located at 2175 Keetak Street off Highway 89 in Meyers, CA.
All off-site boat inspections stations close for the season at the end of September. Winter boat inspections will be performed at the Cave Rock and Lake Forest boat ramps from 6 a.m. until 4 p.m. seven days a week. TahoeBoatInspections.com
Boat inspectors recently prevented two vessels from launching at Lake Tahoe and other regional lakes, after discovering infestations of aquatic invasive species (AIS). During mandatory inspections in Meyers and Truckee, California, inspectors found invasive mussels on both boats.
Inspectors intercepted the first boat at the inspection Station in Meyers, California. The powerboat was coming to Lake Tahoe from Lake Pleasant, Arizona. Discovered on the boat’s hull were some 100 invasive mussels, many suspected to be alive. Inspectors treated and killed the mussels during the decontamination process, but the infestation was so large that inspectors could not remove all the mussels from the boat’s hull and other hard-to-reach areas. The watercraft was not allowed to launch.
In the second case, inspectors in Truckee, California intercepted a small nonmotorized sailboat that contained approximately 20 dead mussels. The mussels were found inside of the sailboat’s keel locker on the hull. The owner stated the boat had been out of the water for about four years, and that he had unknowingly purchased the boat with the mussels already onboard.
“This is a stark reminder of why inspections are mandatory at Lake Tahoe. Aquatic invasive species pose a serious threat and we rely on the hard work and diligence of our boat inspection team to protect Lake Tahoe and other waterbodies,” said Chris Kilian, Tahoe Resource Conservation District.
- Both vessels were intercepted by inspectors before they could launch into local waterbodies.
- Both boats were quarantined for further inspection and decontamination.
- Regarding the boat from Arizona, the mussels lived through the 700-mile, 12-hour trip to Tahoe.
- Deemed to be a high-risk vessel, California Department of Fish and Wildlife required a mechanic to take apart the powerboat’s drive to remove potentially live mussels. The craft was returned to Arizona, and never launched in Lake Tahoe.
- The sailboat was eventually cleared from quarantine and allowed to launch at Donner Lake.
Tahoe Regional Planning Agency’s aquatic resources program manager Dennis Zabaglo said, “In both instances, inspectors on the front-line kept watercraft from potentially harming Lake Tahoe’s fragile ecosystem. These incidents underscore the need for boaters to arrive at inspection stations with their craft clean, drained, and dried.”
In the last 11 years, the Lake Tahoe Watercraft Inspection Program has been successful in preventing the spread of aquatic invasive species into Lake Tahoe and other waterbodies in the Region. Once introduced, species like quagga and zebra mussels would have devastating consequences for the ecosystem and economy.

While it felt like spring had finally arrived, we all know Mother Nature can be fickle, especially at Lake Tahoe.
For those who love to play in the snow, it was a fantastic winter, and a banner year for the Sierra snowpack. Despite some cooler weather now, steady warmer temperatures are on the way and our attention is shifting from the mountains to the lake.
Boating season is here, and our ongoing battle in the fight against aquatic invasive species continues. For 11 years, more than 40 agencies and private nonprofit partners have worked to prevent the further spread of aquatic invasives.
The Tahoe Regional Planning Agency and our partners at the Tahoe Resource Conservation District are operating boat inspection stations around the basin. To date, we have been successful in this critical program. No discoveries of new aquatic invasive species have been detected over the last 10 years.
In no small measure, that’s thanks to the engagement of the boating community. Mandatory inspections have so far stopped the spread of aquatic invasive species like quagga and zebra mussels from entering Tahoe’s waters.
The mantra is simple: clean, drain, dry. Everyone launching a vessel at Lake Tahoe, whether it’s motorized or muscle powered, should be proactive in cleaning watercraft thoroughly. Once you clean it, make sure it’s drained and then fully dry before setting out. Research has shown that adult zebra mussels can survive for days out of water.
During the 2018 boating season, inspectors examined some 8,000 watercraft. Forty-four percent of those had been cleaned, drained and dried. But that means 56% of boaters and their vessels arrived at inspection stations with the potential to spread aquatic invasive species to Tahoe’s waters.
Were either of these invasive mussels able to take hold in Tahoe’s waters, their impacts could be catastrophic. Invasive mussels starve native aquatic species of nutrients they need to survive. Both quagga and zebra mussels are prolific procreators, quickly accumulating on underwater surfaces, encrusting docks, boats, and buoys. Their razor-like shells can carpet shallow waters and beaches, making for a painful encounter with the human foot.
There are harrowing examples of what could have been. Last July, Tahoe Resource Conservation District inspectors intercepted a boat infested with multiple aquatic invasive species. An undetected crack in the boat’s pontoon was allowing water to seep in. Inspectors found adult quagga and zebra mussels, and other aquatic plants and snails — a glaring example of how easy it is for an unsuspecting boater to introduce aquatic invasive species to Tahoe’s ecosystem.
While powerboats get most of the attention, local kayakers, paddle boarders, and other non-motorized watercraft users can also unintentionally introduce invasives to the lake. The League to Save Lake Tahoe’s “Eyes on the Lake” program has educated thousands of lake lovers, enlisting an army of citizen scientists to help monitor the lake’s shoreline and report sightings of invasive plants like watermilfoil and curlyleaf pondweed.
The League will offer several “Eyes on the Lake” training classes throughout the summer. Already, 3,000 people have been trained to keep an eye on Tahoe, helping to protect our clear and pristine waters. The Tahoe Keepers program also has enlisted thousands of paddlers in the quest to protect the lake.
Ground zero in the fight against invasive plants is the Tahoe Keys. The area continues to see large-scale infestations of invasive plants so severe that it’s threatening the entire lake.
In a genuinely collaborative undertaking, the Tahoe Keys Property Owners Association (TKPOA) has partnered with multiple organizations to develop a comprehensive plan to stop the spread of invasive plants. Last month, the property association provided the Tahoe Regional Planning Agency’s Governing Board with an update on the testing to be done in the Tahoe Keys over the next two years.
Testbed studies will be undertaken, using a variety of methods, including the continued application of underwater barriers and the testing of ultraviolet light treatments. The question of whether to use EPA-approved aquatic herbicides is still under discussion and review as part of the testing process over the next few years.
In the meantime, TKPOA and its partners are taking proactive measures to contain these invasive plants within the Keys’ borders. For a second summer, a bubble curtain will operate at the entrance to the Keys. Using a powerful stream of air, this curtain technology dislodges pieces of plant material attached to the bottom of watercraft. Pairing with the bubble curtains, TKPOA has also invested in autonomous sea bins to gather the plant material dislodged from boats leaving the marina.
Protecting and preserving Lake Tahoe’s waters is paramount to TRPA’s mission. Stopping the spread of aquatic invasive species at the lake is a daunting task, and collaborative actions will continue to pave the path to success.

The watercraft inspection program is entering its second decade of fighting aquatic invasive species at Lake Tahoe. The first 10 years were successful because of partnerships and support from the community, with no new documented invasions since the inception of the program.
“We are grateful to everyone who supports protecting Lake Tahoe from invasive species, especially the dedication and diligence of the Tahoe Resource Conservation District’s boat inspectors,” said Dennis Zabaglo, Tahoe Regional Planning Agency’s aquatic resources program manager.
All motorized watercraft require an inspection before launching into Lake Tahoe, Fallen Leaf Lake, Echo Lake, and Donner Lake. Invasive species, such as quagga mussels, New Zealand mudsnails, and hydrilla, are known to quickly colonize underwater surfaces. Knowingly transporting aquatic invasive species into Lake Tahoe is against the law, and violators are subject to fines.
This year, the annual watercraft inspection fee schedule is being simplified, condensing 13 categories to five to make it easier to understand and more accurately reflect inspection work and boat complexity. Decontamination fees were also modified to reflect the work it takes to decontaminate watercraft. To find out how the new fee schedule affects you, please visit: tahoeboatinspections.com
Remember, before arriving at inspections stations: Clean, Drain, and Dry your watercraft. “Save time and money by making sure to drain all water from the intake systems, clean out your vessel, and make sure it is dry,” advises Chris Kilian, AIS program manager for the Tahoe Resource Conservation District.
Transporting boats on roads in the Lake Tahoe Basin and the state of Nevada requires bilge plugs to be removed from the vessel. Draining watercraft during transit helps prevent the spread of aquatic invasive species. Boaters on the water should fill and drain ballast tanks in the same location, making sure they are at least 200 feet from shore.
Invasive species are highly opportunistic, and non-motorized watercraft are also capable of transporting aquatic invasive species. The Tahoe Keepers program informs the paddling community about the importance of inspecting their equipment, keeping Kayaks, paddleboards, fishing equipment, inflatable water toys, and life jackets from spreading invasive species.
